The processing mechanism of the utility model hybrid reaction treatment unit:
1. cohesion
Colloidal type contamination particle in the water is kept the outstanding free state of stable dispersion because it has zeta-potential, the outside medicine machine that this hybrid reaction treatment unit connects by water inlet pipe arrangement dosing coagulant in the sewage, a large amount of high price positive ions that coagulating agent provides can enter diffusion layer even the adsorption layer of colloidal type contamination particle, the combined potential surperficial because of glue nuclear is constant, increase the cation concentration in diffusion layer and the adsorption layer, just make diffusion layer and adsorption layer attenuate, zeta-potential reduces, spacing during collision is dwindled, the repulsive energy peak reduces, magnetism increases each other, and micelle takes off steady and produces cohesion.
2. throwing out
The flocculation agent that this hybrid reaction treatment unit adds has linear structure, can be by colloid pollution particle strong adsorption, because of its lineal measure bigger, after its end adsorbed a certain micelle, the other end adsorbed another micelle again, carried out adsorption bridging between two micelles of apart from each other, particle is tied greatly gradually, form big flocs unit, the particulates such as colloid in catchmenting be caught, be rolled up to flocs unit can also by net in the sinking process.Simultaneously, the spiral of this hybrid reaction treatment unit by the coagulant aids pipe arrangement adds and the baffling effect of tracery wall plate and baffle plate, improved coagulation effect better.
3. precipitating action
The settling region of this hybrid reaction treatment unit is located at the bottom in hybrid reaction district in the housing, muddy water after the flocculation enters the settling region through water distribution orifice plate uniform water distribution, precipitate to be similar to the rectangular sedimentation tank mode earlier, big flco sinks to the bottom of cone naturally, and flco less or that do not have enough time to precipitate then enters swash plate or inclined tube zone precipitation.
The principle of work of the utility model apparatus for treating sewage:
The sewage that the water inlet equipment of housing 3 outer setting is sent into enters into water pipe arrangement 10 with the coagulating agent that the medicine machine of housing 3 outer setting adds, be mixed into the I district through the 10 spiral water distributions of water inlet pipe arrangement, enter the II district through first baffle plate, 11 bafflings then, coagulant aids is added to coagulant aids pipe arrangement 12 by the coagulant aids adding equipment of housing 3 outer setting and also enters the II district, mixed water enters the III district, through entering the flocculation of IV district behind the mixing of tracery wall plate 6 bafflings and longitudinal baffle 5 bafflings, behind the 4th baffle plate 7 bafflings, enter the flocculation of V district, behind the 3rd baffle plate 8 bafflings, enter water distributing area by crossing water window 15, behind water distribution orifice plate 14 uniform water distributions, enter settling region, bracing frame 19 bottom.The energy dissipating plate 20 that utilize to arrange simultaneously reduces the impact of current, keeps the steady precipitation of settling region, and big flco sinks to the cone base of housing 3 by natural sedimentation, and flco less or that do not have enough time to precipitate then enters swash plate or inclined tube filler 16 zones are precipitated.The clear water of post precipitation is discharged outside the housing 3 by the rising pipe 2 that is connected with water leg 1 by in the water leg 1 that a side arranges in swash plate or inclined tube filler 16 upper shell 3, finishes whole water treatment procedure.The mud that produces in the device is discharged housing 3 by the shore pipe 21 that links to each other with housing 3 cone bases.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
